Abstract

La présente invention concerne un procédé et appareil permettant de déduire une représentation d'une image en traitant des signaux correspondant à l'image. Le procédé consiste à déduire une fonction bidimensionnelle (T(d, θ)), comme une transformation de Trace de l'image, et décomposer, par exemple par sous-échantillonnage, la fonction bidimensionnelle (T(d, θ)) dans au moins une de ses deux dimensions, afin d'obtenir une transformation de Trace à résolution réduite. La fonction bidimensionnelle décomposée est ensuite utilisée pour déduire la représentation de l'image.
